The other party used to reply as soon as they saw the text message, but now they call as soon as they see it. Does that mean he doesn't want to ink with you now?

That depends on the tone of his call. If it is good, it means that he cares about you more and more. He used to send text messages, but now he may be embarrassed to call, which shows that things between you are better than before. As for answering the text message very late, he told you that he was watching a movie with the opposite sex, which showed that he was quite honest with you and didn't mean to come back late. You may be special to him, but it's hard to say whether you can become a couple in the end. Maybe he just regards you as a good confidante, so you should also pay attention to your own discretion.
